The development of electrodes composed of non-noble-metal catalysts with both excellent activity and high stability for the hydrogen evolution reaction (HER) is essential for hydrogen production. In this work, a flexible and robust film electrode based on cobalt nanoparticles embedded into the interlamination of N-doped graphene film (Co@NGF) is fabricated by simple vacuum filtration combined w...

Neutron-rich Zr and Mo isotopes were populated as fission fragments produced by the 238Usa, fd fusionfission reaction. The level schemes of these nuclei have been extended beyond the first band crossing region, which can be ascribed to the h11/2 neutron pair alignment. The spin alignment and signature splitting for the nh11/2 orbitals in term of triaxiality is addressed. The crossing frequency ...

A one-dimensional harmonic oscillator in a box is used to introduce the oblique-basis concept. The method is extended to the nuclear shell model by combining traditional spherical states, which yield a diagonal representation of the usual single-particle interaction, with collective configurations that track deformation. An application to 24Mg, using the realistic two-body interaction of Wilden...

The preparation and characterization of new Ru(II) polypyridylbased chromophore−catalyst assemblies, [(4,4′-PO3H2-bpy)2Ru(4-Mebpy-4′-epic)Ru(bda)(pic)] (1, bpy = 2,2′-bipyridine; 4-Mebpy-4′-epic = 4-(4-methylbipyridin-4′-yl-ethyl)-pyridine; bda = 2,2′-bipyridine-6,6′-dicarboxylate; pic = 4-picoline), and [(bpy)2Ru(4-Mebpy-4′-epic)Ru(bda)(pic)] (1′) are described, as is the application of 1 in a...

This paper presents an optimisation model for the synthesis of heat exchanger networks (HEN) including the detailed design of the equipments formulated as a decomposition method. Shell and tube pressure drops and fouling are considered, as well as mechanical aspects, like shell and tube bundle diameters, internal and external diameter of tubes, number of tubes, number of baffles, number of shel...

The calcitic prismatic units forming the outer shell of the bivalve Pinctada margaritifera have been analysed using scanning electron microscopy-electron back-scatter diffraction, transmission electron microscopy and atomic force microscopy. In the initial stages of growth, the individual prismatic units are single crystals. Their crystalline orientation is not consistent but rather changes gra...

Fundamental knowledge on intrinsic plutonium colloids is important for the prediction of plutonium behaviour in the geosphere and in engineered systems. The first synthetic route to obtain salt-free intrinsic plutonium colloids by ultrasonic treatment of PuO2 suspensions in pure water is reported. Kinetics showed that both chemical and mechanical effects of ultrasound contribute to the mechanis...

Perturbative and non-perturbative aspects of differential cross-sections close to a kinematic threshold are studied applying “dressed gluon exponentiation” (DGE). The factorization property of soft and collinear gluon radiation is demonstrated using the light-cone axial gauge: it is shown that the singular part of the squared matrix element for the emission of an off-shell gluon off a nearly on...

The magnetic properties of strained thin films of gadolinium are characterized by a wave vector and thickness dependence of the exchange splitting. The spin-resolved band structure has been mapped by spin polarized photoemission, and provides considerable insight into the relationship between magnetism of local moment systems, and band structure. For more than 30 years theorists [l] have predic...
